Meet the Dentists

Dr. Peter Barnett

Born and raised in New York City, Dr. Peter Barnett spent many hours with his grandparents who were both dentists. He has spent the last 40 years in dental and health care management. He is a recognized leader in the dental insurance industry, as well as a respected businessman owning and managing practices for many years in the northeast and now in Texas. Dr. Barnett provides almost 40 years of experience and knowledge into his care of our patients. His philosophy is that all dentistry is cosmetic dentistry – with the goal of giving patients results that are not only functional but are also appealing to the eye. He strives to give his patients the best treatment available today to maintain healthy, functional teeth, while also recognizing his patient’s desire to improve their smiles. Dr. Barnett also focuses on the treatment of head, neck and jaw joint muscles and the nerve system that allows the jaw to function – through his Texas Headache Relief program. Additionally, Dr. Barnett offers an Airway Management program (also known as sleep dentistry) to help patients with moderate to mild sleep apnea. As periodontal disease can greatly impact the overall health of your mouth and entire body, Star Ranch Dental diligently educates on and delivers treatment programs designed to help patients eradicate the disease and maintain healthier gums for life. Our perio program is led and continually developed by Dr. Barnett. Dr. Barnett offers a level of expertise and experience our patients have come to rely on – and so can you.

Dr. Courtney Geiger
